Question
The equation 4NH35O2 → 4NO + 6H2O represents the catalytic oxidation of ammonia. If 100 cm3of ammonia is used, calculate the volume of oxygen required to oxidise the ammonia completely.
Solution
4NH3 + 5O2 → 4NO + 6H2O
4 vol : 5 vol 4 vol : Nil
If 4 volumes of NH3 requires = `5/4` x 100
= 125 cm3 oxygen.
